Title:
CAM PHASE ADJUSTER
Document Type and Number:
WIPO Patent Application WO/2022/141637
Kind Code:
A1
Abstract:
A cam phase adjuster, comprising a stator (10) and a rotor (20); the stator (10) surrounds the radial outer side of the rotor (20), the stator (10) is provided with stator blades (12) extending radially inwards, the rotor (20) is provided with rotor blades (22) extending radially outwards, and the stator blades (12) and the rotor blades (22) are opposite each other in a circumferential direction so as to form hydraulic cavities therebetween; and the rotor (20) can rotate relative to the stator (10) to a limit position where the rotor blades (22) are closest to the stator blades (12) in the circumferential direction and can be locked at the limit position. The cam phase adjuster further comprises elastic buffering members (30), and when the rotor (20) is located at the limit position, the elastic buffering members (30) can elastically abut between the stator blades (12) and the rotor blades (22) in a rotation direction. The cam phase adjuster can reduce vibration noise.
